Serena Williams is the latest celebrity to join Colin Kaepernick in donating to charities across the country.

Kaepernick is close to fulfilling his goal of donating $1 million to charity and is rounding out the effort with a series of $10,000 donations that will be matched by various celebrities. Stephen Curry, Kevin Durant, Snoop Dogg and actor Jesse Williams were the first four to participate.

Kaepernick and Willams are donating to a Los Angeles-based organization called Imagine LA, which helps homeless families.
